Description RamaKasturi 2015-11-03 09:00:17 UTC
Description of problem:
Files need not be signed when they are in hot tier because if there is no I/0 happening on that file , file will get demoted and it will be signed there. So  signing a file in both hot tier and cold tier is not required.

Version-Release number of selected component (if applicable):
glusterfs-3.7.5-5.el6rhs.x86_64

How reproducible:


Steps to Reproduce:
1. Create a tiered volume
2. Now enable bit rot on that volume.
3. Fuse  mount the volume and create some files.

Actual results:
After 120 sec since there is no I/O happening on that file, the file will be signed.


Expected results:
Files need not be signed when they are in hot tier because if there is no I/0 happening on that file , file will get demoted and it will be signed once it si in the cold tier. So simply signing a file in both hot tier and cold tier will utilize the system resources.
